I Modified My Angle Grinder Stand

It has been awhile since I last posted on this site and with all those times of my absence, I thought I was able to completely change my way of doing things, I was wrong, and one day I found myself again messing with stuffs. Here I am again, this time doing things a little bit user friendly.

I added a foot switch for a pleasant on/off switch.

A bit simple look!

 Installed a butterfly nut for quick releasing the grinder, much secured.

My Pedal Assist Bike

My neighbor's kid had an electric motorcycle that has been sitting idle in the backyard for awhile. The bike ended its life after the speed controller gave up. The cost of the part could not justify the  use of it. One thing is he already outgrown the toy. I decided to give it another life in a different form.

 Trying to salvage the main frame. 

 Added a small basket to hold the battery.

 I used two swivel casters, one caster I have to bore the middle part.

There you go as it is almost completed.

HandCrank FlashLight

I wonder how this little handcrank flashlight works. They say its cheap and simply made. Sure enough we have the idea on how it works, but inside that plastic case we don't really know how it ticks.

This little wonder sealed by the plastic case. Picture taken on each sides.

Took it apart, picture in opposite sides with main parts showing the crank, gear, light assembly.

My Cassette Radio To Iphone Conversion

Here is an old Radio Shack cassette tape recorder that has been lying around my house. 

 The back information says it uses a six "C" cell batteries.

 

 

 Exposing the circuit.

 

 I removed the unwanted cassette mchanism.

 

 I then soldered the speaker cable to a low impedance circuit. 

 Using the touch method, locate the input circuit. This should be somewhere near the cassette head connector. When touched, it should not create a loud humming sound than the rest of the circuit. You can series a capacitor to be safe.

 Short together the main power and the motor power.

 

 Add an on/off power switch.

Just like the simple toggle switch above which I super glued from the inside.

 

And presto! There goes my Iphone radio.
